T 0 all chom it may concern:

v Be it known that I. CARL CUn'r Honxic... a citlzen of the Republic of Swltze-rland. resldlng at Parkstrasse SS5. Baden. Switzen.

land. have invented certain new and useful Improvements in and Relating to the Speed Regulation of Electrically-Driven R1ng- Spinning Frames; and I do hereby declare erence markedrthereon. which forma part of this specification.

This invention relates to the speed regulation of spinning frames, particularly electrically driven ring spinning'frames.

The yarn spun on ring spinning frames is generally wound on bobbins or tubes in conical layers with slightly crossed threads. enabling unwinding to take place without entanglement. To this end the yarn is guided up and down along the rotating spindles by the ringrail which performs a reciprocating up and down motion. At the beginning of the spinning a conical base 'must be wound on the bare tube or bobbin. 'unless the bobbin itself 18 formed with a conicalbase. On the top of this base a firm cop is then built up with normal conical layers. For'this purpose the ringrail must be raised by the thickness of onelayer after each up and down motion and'practically by the whole length of a bobbin or cop from starting" until doflina. This is accomplished by the coppine' motion frame which is reciprocated by an actuating cam and is provided with a ratchet wheel which is moved forward one step at each reciprocation of the frame in the ordinary manner to raise the ring railby the thickness of one layer. a

In accordance with my invention I provide a regulating gear for regulating the speed of the spinning frame which is so constructed and arranged that the speed is caused to rise and fall in accordancewith layers are wound on the'bobbin in such. a

' closely interconnected.

frame, or as I prefer to call it. the speed of the base line, is progressively increasing during a portion of the spinning operation or in a ring spinning frame as succeeding layers are wound on the conical base. This involves a.'n0vel mode of operation which constitutes an important feature of my invention. 5 a

Inan electrically driven spinning frame the regulating gear is preferably arranged to control the speed of the motor which drives the whole machine and in order that the speed may be varied to suit the-winding process, I prefer to derive the speed regulation of the motor in some way or other from the mechanism which controls the motion of the ringrail. Thus the actions of the machine and of the motor would be controlling members however may not be transferred immediately and separately to the regulating gear of the motor, because theinertia of the mass of the motor and of the ring spinning frame have to be taken into account. and in consequence thereof in order to' obtain the most correct regulation of the motor the regulating gear must have first a reciprocating motion somewhat in advance of the motion of the ringrail at the freversin )oints. and secondlv a oroe'ressive motion. to suit the fullness ofv the bobbins. but not uniformly progressive as the motion f the ring'rail.

The main object of this invention is to cause the speed of the spinning frame to vary in accordance with the rise and fall of the ring'rail and to progressively increase as successive layers are wound on the bobbin so that the speed of the base line corresponding to the lowest position of the ring" rail in its reciprocating motion is progressively increased during aportion of the spinning operation and more specifically to transform the motions introduced by the above-named members of a machine of the type referred to above anl combine them so that the resulting motion of the last member of the apparatus according to this invention communicates to the the motion requisite for correct speed regu lation of motor.

The motion of the regulating gear f The invention comprises a novel mode of \aryflin the dcsireitl i moor and more spe rih'cally consists in a'reggi ulating'appamtns to g on; with electrically driven ring; frames.

so; that two diil erent motions are trans formed and cornlnne H1 a Sllltfllllt'. manner, one of which niatioi derived from o member of the spinning machine 'Wllltfll'l pro; times the reciprocating motion of the ring; rail or from any other suitable member which causes or receives an cquiralentniotion, the other being haired from a member producing the n-ogressive motion of the ringrail or any member which causes or to ceives an cquivrhiuit motion in order to con-- trol by the resulting: inotion an apparatus which regulates the speed Oil the driving motor: M j i The invention also UllltJiSES in a regulating apparatus of t hind referreifl to-ahoro which communicates the orient the two n1otionsfroni the shaft of the ca-ln of the copping motion or from any part rotating with. same. and the other or thetwo motions $0111 the axle of the ratchet wheel or any part ro tilting with same to the regulatii-ig gear.

The invention also consists in a regulating; apparatus of t-hehind referred to above arranged so that of the motionsis transformed by this apparatus into a motion similar and related to the reciprocating mo tion of the ringrail, but which takes into account the inertia of the masses of. the

motor and the machine in atlmnec of the reciprocating motion of the nmohine hetween'the reversing points. a r i a The inrention also consists 111 the improved regulating arrangements for eleclllCHll}? driven spinning. frames hereinafter described.

Referring to mgs-F1gure 1-diagraminatica-lly shows an arrangement according to one form of the invention. and Fig. 2 is a curve showing the relation between time and speed of the spun dle,,accortling to one form of the invention. a

In carrying the invention into oti'oct according to the form illustrated in Fig. 1, the motion of the ringrail is governed by the lover a on the machine by means. for example, of a chain Z), The cam c of themachinesets up a recipro-ating motion in the lever, the chain. and the ringrail. After each up and down motion the ratchet wheel (I, which is lixed on the end of. a shaft carried by the lever 01.. is rotated one tooth.

by means of pawl 10 intermittently. thereby causing the controlling: chain 1. to he wound mrthe shaft r? of the ratchet wheel. and consequentlva lifting: of the ringrrail. Due to the ac'ljhal motion of the'ringr-rail resulting from theabove reciprocating and progresiscd to the accompanying drowi117 we? made. The a maratus.

'lhere are several important ad'anta'ges attending the use ofan apparatuses described ahove among which ay be men tinned: The appuratuscannot tall out ot stop. One set, it is inipossihle that the motor would regulated in any. otherway than that to suit the different phases oithe winding process. Any change in theflposition of the ringrail by turning! the ratchet wheel (1 is at oncecoinnnmicated to the regulatingapparatus.

taken care of by positioning the cam so snag-4.47.

that the reciprocating motion of the regulatmg gear will take place somewhatin advance of the motion of the ring railxat'the lBVQllSlllQ points. If. for instance. the roller m allowsthe cord is to hang loosethen the reciprocating motion of'the' l'eveinis notcommunicated at all to the regulating gear and the motor runs at constant speed, being returned to normal position with the handle" 7 against stop 8 by the weight 9. As the roller goes down the amplitude of the re ciprocating motion communicated to It increases more and more until it reaches a maximum, as shown in the firstpa'rt of the curve, Fig. 2. Thereafter the amplitude of the. reciprocating motion remains constant but the speed of the frame maybe increased, as shown in the middle portion of the curve.
